Tasting food is something we do without even thinking about it. Our sense of taste tells us that we like certain foods or that we dislike others. But what is taste exactly and how does it really work? Have you ever stopped to think about the way your brain deciphers this information?

Actually, four "official" categories, salty, sweet, sour, bitter and a fifth "unofficial" one named umami, are involved in the perception of a combination of chemical signals all across the mouth. A mix of food and saliva creates a chemical reaction that stimulates the sensation of taste. Your taste buds, sensory organs located in the mouth, are the ones that send the signal to your brain.

But taste also includes the way food looks as well as how it smells, and those three senses combined maximize the experience. Therefore, there are other components involved like temperature, texture and, of course, flavor. Those are the foundation for food preferences and they usually begin very early in life, even before birth. There are four main factors that intervene:

  • Environmental influences (cultures, social classes, etc.)
  • Learned behaviors (food preferences)
  • Mother influences (what our mother ate or drank while pregnant and breastfeeding)
  • Innate factors (the instinct that tells us that the food isn't good anymore)

There is also a common misconception about taste that says that each part of the tongue specifically perceives a category of tastes. This notion has been demolished in 1974 by a scientist named Virginia Collings. She proved that any type of tastes are equally detectable all over the tongue, although certains areas of the tongue are more sensitive to a particular kind of tastes.
